Few/1v. f?SU/VOHOLM F' 3, I BY Patented June 23, 1953 METHOD- F PRODUCINGDISCHARGE HEADS AND--HANDLE SUPPORTS FOR BARREL PUMPS Edwin F. Sundholm,Albert City, Iowa Application J nuaryf'so, 1950, serial No. 141,259 rThe present invention relates to a new and improved liquid-dispensingapparatus and more particularly to a barrel-pump forremoving'lubrieating-fluid from a container such as a 55-gallon drum orthe like.

The present invention relates more particularly to the method of.constructing the head,- portion or cap-portion of a liquid-dispensingapparatussuch as a barrel-pump.

An object of the present invention; is to provide a new and. improvedmethod of manufacturing the. head-portion or cap-portion of abarrel-pump or similar; liquid-dispensing apparatus. An additionalobject of the present invention is:- to provideamethod of constructingthe -head-portion of a liquid-dispensing apparatus such as a barrel-pumpor the like which requires less cost, labor and time thanheretobeforeused. I

, Further objects will be apparent by reference to. the appendedspecification; claim and drawings. I

For the purpose of illustrating the. invention, there is shown in theaccompanying drawings one form thereof which is at present preferred,although it is to beunderstood that the various instrumentalities ofwhich the-invention consists can be variously arranged and organized.and thattli'invention is not limited. to the precise arrangements andorganizations of the instrumentalities as herein shown and described.

Referring to the drawings wherein like reference characters indicatelike parts:

"Figure I represents a perspective view, partly insection, or thebarrel-pump of'the present. invention as employed on alubricant-container. V Figure 2" represents" a side elevational view,partly in section, of'th'e barrel-portion and capportion. ofthe'lubricant dispenser of the present invention supported on theheadiof a lubricant container. 7

.Figure 3' represents a Vertical cross-sectional 1 Claim; ((31. 29-1564)ilar. to the pump. contemplated by the present invention is disclosed.in Sundhol'm Patent 2,344,005. Such pumps. may be. supplied to re- 1tailers of lubricating fluid or to large-scale consumers of lubricating.fiuid;.said retailers or conto. dispense the fluid therefromintermittently in View of the cap-portion of the barrel pump smallamounts.

To facilitate the removal of the lubricant from the container, thebarrel-pump contemplated by the present inventionImay be employed, whichpump generally includes. a cylindrical barrel por: tion withreciprocatingpiston therein'secured to the drum-head at the bung-holeopening, with a riser-pipe extending into the container andiwithhandle-means to operate the piston and with. a spout or conduitthroughwhich the contentsof the barrel may be discharged.

In Figure. 1 thereis shown a pump. ID of the type contemplated. by thepresent. invention. This pump. includesa. cylindrical. barrel-portion ll which maybe screw-threaded at its lower end. l2 for engagement with. abung-hole. adapter I3. Said bung-hole adapter may. be screwthreadedlysecured in the bung-hole M in one end [5. of a lubricant container 16. Ariser-pipe bottomof the lubricant-container. Appropriate valvemeans-such as a foot-valve (-not shown),

may be disposed in the lower end of. the riserpipe near the bottom ofthe; container l6-or at the upper end of the riser-pipe within theadapter. I3, through which lubricant may be drawn into the barrel-memberll.

A. piston I 9 is adapted. to fit slidingl'y fluidetight relationshipwithin the barrel: H and to be reciprocated therewithin by thepiston-rod 20; The upper end of. the piston-rod 20. extends out of thebarrel. I I through the cap or head 2| and is secured, at its upper end,to the handle 22. The handle 22 may be joined by the link 23 i 7 curedto and extending upwardly and outwardly from the cap or head 2|. Bymeans ofv the handle 22 and link 23, the piston-rod 20 and piston [9 maybe reciprocated axially within the barrel It].

The cap or head 2| preferably is shaped and and. in

formed from a piece of sheet-metal into the cuplike body 53 with aflange 54 having screwthreads 33 adapted to receive the barrel lltherein, and having a central hole 29 at the upper end to receive apacking-gland '25 and with an aperture 31 on one side thereof to receivea spout The packing-gland '25 is secured to the cap or head 2l aroundthe piston-rod to provide a sliding seal between the piston-rod 20 andthe head 2|. The packing-gland includes a member 26 having a flange 21and screw-threads 28. The

member 26 is adapted to fit within the aperture 29 in the cup-like body53 with the flange 21 in contact with the outer surface thereof 7 Thebody-member 26 may be secured to the cup-like body 53 by brazing orsoldering or welding or any other suitable means whereby to provide afluid-tight seal between the body 53 and the member 29. The piston-rod29 is adapted to pass through the hole 30 in the bottom of the member25, and suitable packing-material 3| (such as a neoprene seal or fiberor jute washers or the like) in the member 28 is compressed by the nut32 (which is engaged in the screw threads 28) around the piston-rod 20whereby .to provide a fluid-tight yet slidable seal between thepacking-gland 25 and the piston-rod 20.

' The cap or head 2| may be screw-threadedly secured to the barrel H asby the threads 33 with a gasket 34 providing a fluid-tight seal betweenthe barrel ll and the flange 54.

A conduit or spout 35, having external screwthreads 36 at the endthereof adapted to" receive a discharge hose or the like (not shown),extends angularly upwardly and outwardly from the cuplike body 53through the aperture 31 therein. The spout may be brazed or welded orsoldered or otherwise secured in a fluid-tight fashion to the body 53.

The supporting-bracket for the handle 22 and the link 23 preferably isstamped or otherwise formed from one piece of sheet-metal into a pair ofarms 4! and 42 having flanges 43 and 44, respectively, and-formed, attheir juncture,- point, into the cylindrical bearing portion 45 which isadapted to receive the pivot pin 46 to which'the link 23 may be secured.The arms 91 and 92 may be reinforced by' the ridges 41 and 48,respectively, to provide an inexpensive sturdy and light-weightbearing-member or support-bracket for the handle 24.

The flanges 43 and 44 on the arms 4! and 42 according to the'methoddescribed herein produces a pump which is lighter in weight and henceeasier to handle and less expensive to transport than barrel-pumpsheretofore used.

The present invention may be embodied in other specific forms withoutdeparting from the spirit or essential attributes thereof, and it istherefore desired that the present embodiment I be considered in allrespects as illustrative and may be projection-welded or spot-welded tothe Y cup-like body-member 53 as at 49, 50, 5| and 52.

I have found that a barrel-pump can be manufactured quiteinexpensivelywhen the pump-cap V or pump-headof the present invention isused therein. The sheet-steel cup-like body-member 53 may be formed muchless expensively than cast-iron or cast-steel body-members heretoforeemployed and the bracket 24, being a pressedsteel one-piece membersecured to the discharge} head 2| by the rapid and inexpensiveprojectionwelding method is much less expensive to fabrinot restrictive,reference being had to the appended claim rather than to the foregoingdescription to indicate the scope of the invention. Having thusdescribed my invention, what I claim as new and desire to protect byLetters Patent'is the following:

" The method of producing a discharge head and handle-support for abarrel pump which corn prises pressing a cup from apiece of flatsheet-'- stee1,'cutting screw-threads on the inner surface of the lip ofsaid cup, punching an aperture in r the center of the end wall of saidcupanda second aperture in the side of said cup, bending agenerally'J-shaped discharge spout from a onepiece tubular pipe, brazingthe longer end of said spout in fluid-tight manner to said cup 'at' saidsecond-named aperture with the bore'of said spout in communication withthe interior of said cup, brazing a packing-gland tosaid cup at saidfirst-named aperture,bending a one-piece generally V-shaped bifurcatedbracket from flat sheet-steel to form a self-container pivot-bear ing atthe root of the V and to formcup-engaging flanges at the ends of the V;and projection welding said bracket-flanges to the outer surface of theside of said cup opposite said secondnamed aperture.
